Hughes' expression was like a deer cought in headlights halfway through the first round when he discovered he couldn't out-strike, out-wrestle, or take BJ down like he's used to doing with other opponents.
2nd round BJ was even more impressive with BJ completely dominating Hughes. Hughes was saved by the bell in the first and second rounds.
Third round BJ walked in obviously injured, he couldn't move. It's not hard to beat someone when they can't move, hence luck on Hughes' side for the win. Round 3 was the only time Hughes did anything in the fight, and it was against an injured BJ.
Separated ribs can happen anytime, and lady luck played her hand to rescue Hughes. I have no idea why Hughes' apologists think he did anything exceptional.
The fact that he defended several submission attempts does not impress me. It would impress me if he actually attempted some submissions. It's like the lion and the zebra. just because the zebra outruns the lion 9 out of 10 times, doesn't make the zebra king of the jungle.
In this fight BJ was the lion, Hughes got lucky plain and simple, hence GSP's coment of Hughes getting the win but not looking impressive holds true.
